Data Usage Reports provide you a weekly snapshot of which of your observations were downloaded in the past week, by whom, and how they were used. If you're curious about how often your observations are used and what they're used for, our Data Usage Reports should give you a broad view of what is happening to your observations that go into the AAVSO International Database. You'll be told how many of your observations of each star were included, whether the person requesting the data[2] is an Amateur, Professional, or Student researcher, and what the requester is planning on using the data for.
